When you land a new job, it's hard to imagine there's any need to update your résumé once again.

Perhaps you just updated it to land the role, and, at the very least, you don't have plans to pursue a new gig after just landing this one.

If you're like most people, you're probably going to wait until something happens that triggers your need to update your résumé.

But Amanda Augustine, the career advice expert for TopResume, says this is the worst time to write your résumé.

"The best time to update your résumé is when you don't need it right away, when there's no pressure or tight deadline hanging over your head," she told Business Insider. "You want to approach the résumé-writing process — whether you're planning to work with a professional résumé-writing service like TopResume or go it alone — when you have access to important information and there aren't any emotions clouding your judgment."

According to a study by TopResume, 73% of employed professionals are open to exploring new job opportunities, even though they enjoy their current job.

But if your résumé isn't up to date, you may not be ready when that opportunity comes your way.

Beth (not her real name) recently got a promotion at work, and she wanted to update her résumé to reflect her new role so she could be ready should an interesting job opportunity come her way.

We asked TC Paulson, a résumé writer withTopResume, to rewrite Beth's résumé now that she's moved into her first management role to help reflect her progression.

With an up-to-date résumé, she'll be prepared should a networking contact or a recruiter reach out with an interesting opportunity, Augustine said.

Overall, TC adjusted the format and presentation of Beth's résumé to make it easier to read and scan through electronic applicant tracking systems. TC also beefed up Beth's résumé to match the strength of her career's trajectory and crafted statements to reflect her creativity, her communications expertise, and her talents in diplomacy.

"This can often be an intangible, yet essential aspect of a résumé for someone in her field of PR," TC told Business Insider.

Augustine explained in more detail some of the specific changes TC made to Beth's résumé to help prepare her for her next step. While your résumé may look different, these pointers should help you overhaul your ownrésumé:

1. Remove the street address

Augustine said she encourages candidates to include their city and state if they're local candidates, but there's no reason to provide additional details about where you live.

"They take up precious space on your résumé and can be considered a security threat — think about all the places you post your résumé online," she said.

2. Add links to social media

TC added a link to Beth's LinkedIn page, while Beth made sure her other relevant social media accounts, such as her Twitter account, were linked to her LinkedIn profile.

"While it's important for most candidates to add LinkedIn to their résumé, it's even more so for Beth, since she is in PR, and social media is a critical area of expertise for her career progression," Augustine said.

3. Create a professional profile

TC created a qualifications profile for Beth "that set the tone for the rest of the résumé," Augustine said.

"The professional title clearly states Beth's current job, leaving no room for ambiguity," Augustine said. "However, the word 'manager' in the title can be swapped out at any time to reflect whatever specific position Beth is targeting."

Below that, TC included Beth's professional summary, which Augustine said gives the reader a sense of Beth's most marketable soft skills and hard skills and the extent of her experience.

"While you might be able to get away with omitting a professional summary from your entry-level résumé, you must include something at the top of your mid-level résumé that summarizes your goals and value proposition," she said.

"Think of it as the place where you incorporate your elevator pitch into your résumé," Augustine said.

4. Highlight language skills

"A proficiency in another language is a good selling point in virtually every role," Augustine said.

TC not only incorporated the word "bilingual" in Beth's professional summary but also listed her language skills in a languages section at the end of her résumé. TC also included the term "fluent" in the languages section to include all the keywords a recruiter or ATS system may be trained to seek out.

5. Optimize résumé with keywords

Based on sample job descriptions of roles Beth might aspire to, TC identified keywords Beth could expect to see in her target job listings and maximized their use throughout her résumé.

TC incorporated these keywords and phrases throughout every section of Beth's résumé, from the "Areas of Expertise" table at the top to the "Technologies" section at the end.

"This technique will also help Beth's résumé pass the robotic screen and advance it to a live person for review," Augustine said.

6. Highlight accomplishments

In describing Beth's experience, TC emphasized her accomplishments over the tasks she was responsible for.

"When you're describing your experience, dedicate a few lines to explain your responsibilities, and then use bullets to accentuate your most important and marketable contributions and achievements," Augustine said.

"Remember, bullet points are tools to attract the reader's eye — use them sparingly," she said.

7. In most cases, remove months from dates

If you ended one job in November 2015 and started the next in January 2016, Augustine said you may want to include the months to indicate there were only two months between your roles.

In Beth's case, though, she said there weren't any major gaps in employment, so TC chose to use only years to represent Beth's tenure.

"By doing so, this also eliminated extra words and gave the design of the résumé a cleaner, less cluttered look," Augustine said.

8. Lengthen the résumé to two pages

Samantha Lee/Business Insider

"At this stage of her career, Beth has several internships and a college degree to promote on her résumé," Augustine said. "Now that she has five years of relevant experience under her belt and a slew of valuable and marketable skills, it's time for Beth to graduate to a two-page résumé length."

9. Name-drop industry leaders

"Even if an ATS scan isn't going to recognize a certain musician, or the significance of a well-known media mogul, we want the hiring manager to notice these names once the résumé reaches her hands," Augustine said.

This was one reason why some of Beth's internship experience was included in her final résumé, she said.

10. Highlight internship experience

"In most cases, once a professional graduates, enters the 'real world,' and racks up a few years of marketable experience, it's time to remove any references of their college career from their résumé, including school activities and internships," Augustine said.

But TC intentionally included some of Beth's internship experience in her résumé.

Augustine explained that, for Beth, her intern roles are important because of the connections she made there.

"It is also important for professionals like Beth to demonstrate that she can work with various organizations, from boutique agencies to large corporations to municipalities," Augustine said.

11. Redesign layout to be more recruiter- and ATS-friendly

"While it may be tempting to jazz up the design of your résumé, it's important to remember that recruiters are accustomed to looking for certain pieces of information in specific areas of a résumé document," Augustine said. "The less time a recruiter spends hunting for information on your résumé, the more likely you are to make it to the next stage of the hiring process."

Augustine said that applicant tracking systems — the bots that scan your résumé and decide if you're a good fit for the position — tend to have trouble reading and parsing résumé information when it doesn't follow a traditional layout.
